Can't view detailed bill

I'm a business customer and I haven't been able view my bill either. I wanted to check why my bill was raised to over $300 a month out of no where, when I was only paying a little over $100. I tried checking on the app first, but it kept spinning. On a Saturday, I logged in from my laptop, and the same thing. I figured that happened because maybe it was a weekend issue. I tried again today, on a Thursday, and same thing.  Funny thing is, I'm able to view the page where they want me to pay, but can't access the detailed view of my bill. I called customer service and of course they're recording online says they're not open yet. This is very frustrating and I'm now checking the prices for Verizon wireless. I too feel as though T-Mobile is scamming their customers. I will NEVER recommend this service to anyone.
